Question

Check all appropriate statements concerning pentyne.
contains exactly 3 carbons
contains exactly 5 carbons
contains exactly 7 carbons
has only single bonds
has a double bond
has a triple bond
is an alkyne
is an alkene
is an alkane

I honestly don't know the difference between the last two, so can you explain that too? Thanks so much!!!

Answer 1

If you remember this much, you'll cruise through organic chemistry :)
The prefixes: 1 - meth
2-eth
3-prop
4-but
5-pent
6-hex
7-hept
8-oct
9-non
10-dec

and for the bonds its: 1 bond - alkane
2 bonds: alkene
3 bonds alkyne :)

Can you match up the prefixes and tell me what you get so i know you understand? :) also, yea as i said before in reply to your final question: alkane have carbon carbon single bonds and alkene have carbon carbon double bonds. good luck!
