Answer 1

Answer:

It is given that an element M reacts with chlorine to form a compound X. The bond angle in X is found to be 120

o

. This implies the compound is trigonal planar molecule of the type MCl

3

. B is the only element among the given elements which has valency 3 and forms trigonal planar halide with chlorine.

Hence, option B is the correct answer.
