Question 12.3 Arrange the following compounds in increasing order of their boiling points.
Answer :
Increasing order in their boiling points-
Alcohol has the highest boiling point due to more extensive intermolecular H-bonding. Aldehyde is more polar than ether so, ethanal has high BP than ethyl ether. And alkane has the lowest BP.
Question 12.4(i) Arrange the following compounds in increasing order of their reactivity in nucleophilic addition reactions.
Ethanal, Propanal, Propanone, Butanone.
Answer :
By the above structure, we can see that, due to +I effect of alkyl group te electron density at Carbonyl carbon increase from ethanal to bytanone. And so the tendency of attacking nucleophile is decreased.
Thus the increasig order (reactivity towards nucleophile)-
Butanone < propanone < propanal < ethanal
Question 12.4(ii) Arrange the following compounds in increasing order of their reactivity in nucleophilic addition reactions.

If +I effect is more its reactivity towards nucleophilic addition is less. and -I is more, more reactive toward addition.
So, according to this concept, increasing order of their reactivity in nucleophilic addition reactions-
Acetophenone < p-tolualdehyde < benzaldehyde <p-nitrobenzaldehyde

Q 12.17 (xi) Complete each synthesis by giving missing starting material, reagent or products.
Answer:
The above reaction is ozonolysis reaction in which ozone molecule breaks the double bond of the alkene and formed a ketone or aldehyde as a product.
Q 12.18(i) Give plausible explanation for each of the following:
Cyclohexanone forms cyanohydrin in good yield but 2,2,6-trimethylcyclohexanone does not.
Answer:
Structure of 2,2,6-trimethylcyclo hexanone
Cyclohexanone forms cyanohydrin when the nucleophile ( ) attack on cyclohexanone.
In this case, there is less hindrance around the CO group so the nucleophile can attack easily. But in case of 2,2,6-trimethylcyclo hexanone at the alpha ( ) position, there is a hindrance because of the methyl groups. Thus the nucleophile cannot attack effectively.
Q 12.18(ii) Give plausible explanation for each of the following:
Answer:
In Semicarbazide,
One of the group is involved in resonance with the carbonyl group, which is directly attached. Therefore, it cannot act as a nucleophile (its electrons are less available or less electron density at that group). But the other group is not participating in resonance, so it can act as nucleophile and attack on the carbonyl carbon of ketone and aldehyde.
Q 12.18(iii) Give plausible explanation for each of the following:
Answer:
If either water or the ester is not removed immediately then ester can react with water and again and give back the reactants.
Thus to shift the reaction in forward direction we need to produce more ester or remove either of the two.
Answer:
In the question, it is given that,
% of carbon = 69.77
% of Hydrogen = 11.63
% of Oxygen = (100-69.77-11.63) = 18.6
Now, the no. of moles of the components are-
Thus ration of C:H:O = 5.81:11.63:1.16
To get empirical formula we need to divide them by 1.16 .So,
C:H:O= 5:10:1
So, the empirical formula is
The molecular mass of the compound =
Since the compound does not give tollens test it means it is not an aldehyde. It is given that, the compound gives positive iodoform test it means the compound must be methyl ketone.
On oxidation, it gives ethanoic acid and propanoic acids. Therefore, the compound should be
Pentan-2-one
the structure of the compound is -
Answer:
In carboxylate ion the electron is delocalised between oxygen, which is electronegative in nature. But in case of phenoxide ion, the electron are delocalise between less electronegative atom and also phenoxide ion has non-equivalent resonance structure. Therefore, carboxylate ion is more resonance stable than phenoxide ion and we know that more stable the conjugate base of an acid, high strong is the acidic

hello,
Yes you can appear for the compartment paper again since CBSE gives three chances to a candidate to clear his/her exams so you still have two more attempts. However, you can appear for your improvement paper for all subjects but you cannot appear for the ones in which you have failed.
I hope this was helpful!
Good Luck
Hello dear,
If you was not able to clear 1st compartment and now you giving second compartment so YES, you can go for your improvement exam next year but if a student receives an improvement, they are given the opportunity to retake the boards as a private candidate the following year, but there are some requirements. First, the student must pass all of their subjects; if they received a compartment in any subject, they must then pass the compartment exam before being eligible for the improvement.
As you can registered yourself as private candidate for giving your improvement exam of 12 standard CBSE(Central Board of Secondary Education).For that you have to wait for a whole year which is bit difficult for you.
Positive side of waiting for whole year is you have a whole year to preparing yourself for your examination. You have no distraction or something which may causes your failure in the exams. In whole year you have to stay focused on your 12 standard examination for doing well in it. By this you get a highest marks as a comparison of others.
Believe in Yourself! You can make anything happen
All the very best.
Hello Student,
I appreciate your Interest in education. See the improvement is not restricted to one subject or multiple subjects and we cannot say if improvement in one subject in one year leads to improvement in more subjects in coming year.
You just need to have a revision of all subjects what you have completed in the school. have a revision and practice of subjects and concepts helps you better.
All the best.
