Answer 2

Explanation:

hydrocarbon X

step-by-step explanation:

given that,

The melting points of

hydrocarbon X = -190° C

hydrocarbon Y = -90° C

Clearly,

-90° C > -190° C

Thus,

the melting point of

hydrocarbon Y > hydrocarbon X

now,

we know that,

as the melting point is higher,

it means that molecule has more molecular mass,

it means it has more carbon atoms

so,

hydrocarbon Y has more carbon atoms,

hence,

hydrocarbon X has minimum no. of carbon atoms.
