Question

How many isomers have the formula C3H8?

Answer 1

Well you gots a saturated alkane...

Explanation:

And ONLY the one isomer is possible:

...the straight chain alkane....`H_3C-CH_2CH_3`...on the other hand, saturated butane, `C_4H_10`, can generate 2 isomers, and pentane, `C_5H_12`, can generate 3 isomers. And hexanes can generate 5 isomers. As the chain length grows, the number of isomers multiply substantially...
