Answer 1

Would it not be three?

Explanation:

You gots....

`H_3C-CH_2CH_2CH(OH)CH_3 stackrel(H^+)rarrC_5H_10+H_2O`

So (i), you might have small quantities of the `C1` olefin...

`H_3C-CH_2CH_2CH=CH_2`

And (ii), you might have the `C2` olefin...

`H_3C-CH_2CH=CH-CH_3`...but `E` and `Z` isomers of this olefin are conceivable...so that is three isomers in total....
