Question

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

Answer 1

x=2

Step-by-step 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

`x = 2`

Step-by-step 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`
