Statement (I) : In the case of formaldehyde K is about 2280, due to small substituents, hydration is faster.

Question

Given below are two statements:

Consider the following reaction

Statement (I) : In the case of formaldehyde

K is about 2280, due to small substituents, hydration is faster.

Statement (II) : In the case of trichloro acetaldehyde

K is about 2000 due to – I effect of – Cl.

In the light of the above statements, choose the correct answer from the options given below:

(1) Statement I true but Statement II is false

(2) Both Statement I and Statement II are true

(3) Statement I is false but Statement II is true

(4) Both Statement I and Statement II are false

Answer 1

Correct option is : (2) Both Statement I and Statement II are true

\(k_{eq}\) = 2280 is for HCHO

\(k_{eq}\) = 2000 is for chloral

Both data is given in clayden and warren book.

\(k_{eq} > 1\) because HCHO and chloral are more electrophilic.
