Answer 1

Phosgene(COCl2), mustard gas and tear gas are prepared with chlorine gas.

Answer 2

Chlorine itself is a poisonous gas if its concentrated enough and has been used earlier in warfare.

Some dangerously poisonous compounds that can be formed with chlorine chlorine are as follows:

(a) Phosgene, which is avery poisonous compound with bas odour and was widely used  Worl War I.

(b) Mustard gas, part of the sulphur family which if exposed to skin and lungs, can form blisters and deformities.

They are yellowish in colour and smell somewhat like mustard, hence, mustard gas.
