1) What is the major product of dehydration of an alcohol?
When you remove H2O from an alcohol, you end up with a double bond. Therefore, the product is an alkene, a hydrocarbon with a double bond. Check this out:

R-CH2-CH-R (the alcohol) -------> R-CH=CH-R (the alkene) + H2O
|
OH

2) Why does the simplest ketone have three carbon atoms and no fewer?
A ketone is made up of this structure:

O
||
R-C-R

The simplest one is therefore,

...
