Expert Answer:

Ans. 10
For ethyl benzoate, the aromatic ring has a -CO2CH2CH3 group attached which is an electron withdrawing group. Therefore the electrophilic aromatic substitution reaction will occur at the meta position giving 3-nitrophenyl ethanoate.
 
Ans. 11
A rate of Iodination of benzenes and hexadeuteriobenzene are different because C-D bond is stronger than C-H bond since mass of deuterium is twice that of hydrogen which gives strength in bonding.
Hence, K1>K2
 
Ans.12
Similarly as Ans.10, CN is an deactivating group hence the product obtained is metachlorocynobenzene.
