Question

A hydrocarbon with this formula C2H6:

A) is an alkane
B) is an alkene
C) is an alkyne
D) indeterminate

Answer 1

General formula of alkane is C(n)H(2n+2).
General formula of alkene is C(n)H(2n).
General formula of alkyne is C(n)H(2n-2).
So, C2H6 = C(2)H(2*2+6) =C(2)H(8)

Answer: A. C2H6 is an alkane.

Answer 2

Answer: Option (A) is the correct answer.

Step-by-step explanation:

For alkanes general formula is
`C_(n)H_(2n + 2)`, where n is any integer.

For alkenes general formula is
`C_(n)H_(2n)`, where n is any integer.

For alkynes general formula is
`C_(n)H_(2n - 2)`, where n is any integer.

Since, formula of given hydrocarbon is
`C_(2)H_(6)`. Therefore, here n equals to 1 as
`C_(2)H_(2(2) + 2)` equals
`C_(2)H_(6)`.

Hence, we can conclude that given hydrocarbon is alkane.
