Methane is the first member of the alkane series of hydrocarbons. The second member is ethane.
Which statements about ethane are correct?
1 Ethane has the formula C2H4.
2 Ethane has a higher boiling point than that of methane.
3 Ethane has the same molecular formula as methane.
4 Ethane has chemical properties very similar to those of methane.
A 1, 2 and 3 B 1 and 4 C 2 and 4 D 3 only
Answer: C
Explaination
The chemical properties of all alkanes are same because of same general formula. Their physical properties generally increases like boiling point, melting point, viscosity, molecular masses because of increase intermolecular forces among.
