Question

A gaseous material has a strong smell , evaporates quickly , particularly boils at 33.34°C and melts at -77.73°C. This material can be classified as?

Answer 1

Answer:

NH3.

Explanation:

Since, ammonia has three hydrogen which makes a very strong hydrogen bond with each other leading to its high boiling point and also a very low  melting point.

This, ammonia can also be classified as liquid ammonia which is at -33.34 degree of boiling temperature.It has a higher boiling point than phosphine due to the presence of a covalent bond present between hydrogen and highly electronegative nitrogen with a lone pair and its hydrogen bonds are also stronger then the london dispersion.

Answer 2

Explanation:

i think it's B. mixture
