Answer 5

Ammonia
Ethanol solvent 60°
Ammonia must be in excess for one to acts a nucleophile and some other to act as a base
Amine

Question 6

Why is ethanol added in hydrolysis of halogenoalkanes

Answer 6

To dissolve the halogenoalkanes
As they are insoluble in water

Question 7

Explain the reactivity of halogenoalkanes

Answer 7

Going down the group bond length increases
Bond strength decreases due to the share pair of electrons in the C-hal bond gets further away from nuclei ( c and hal)
The electrostatic attraction between the bonding pair and the nucleus is decreases
