_23rd_January_Evening_Shift_en_20_1.png)
Statement (I): In the case of formaldehyde _23rd_January_Evening_Shift_en_20_2.png)
is about 2280, due to small substituents, hydration is faster.
Statement (II) : In the case of trichloro acetaldehyde _23rd_January_Evening_Shift_en_20_3.png)
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 :
Statement I is true but Statement II is false
Both Statement I and Statement II are true
Statement I is false but Statement II is true
Both Statement I and Statement II are false
Explanation
$\mathrm{k}_{\mathrm{eq}}=2280$ is for HCHO
$\mathrm{k}_{\mathrm{eq}}=2000$ is for chloral
Both data is given in clayden and warren book.
$\mathrm{k}_{\mathrm{eq}}>1$ because HCHO and chloral are more electrophilic.
