Question

An alkane group has a formula of CxH6, determine the value of x​

Answer 1

Answer:

x=2

Explanation:

Because alkanes have a general formula of CnH(2n+2).

We known that 2n+2=6, so we solve for n.

2n+2=6

2n=4

n=2

Thus, there are 2 carbon atoms.

Answer 2

Answer:

$x = 2$

Explanation:

General formula for alkanes

$C _{n}H _{2n + 2}$

since H = 6

$2n + 2 = 6 \\ 2n = 4 \\ n = 2 \\ since \: x = n\\ \therefore \: x = 2$
