What are the functional groups of the following please for ten points!

2-methylpropan-1-ol
2-methylpropanoic acid
Butan-2-ol
But-1-ene
2-methylpropan-2-ol
Butanal
But-1-ene
2-methylpropanal
2-methylpropene
Butanone
But-2-ene
2-methylpropene

You don't have to do all of them if but would appreciate it and give 10 points to whoever helps me with them all! Much appreciated!

2-methylpropan-1-ol the OH bond (primary alcohol)
2-methylpropanoic acid The carboxylic (C,O,OH)
Butan-2-ol The OH (secondary alcohol)
But-1-ene The C=C (C=C-C-C)
2-methylpropan-2-ol The OH bond (tertiary alcohol)
Butanal the carbonyl C=O bond
But-1-ene The C=C Bond (C=C-C-C)
2-methylpropanal The carbonyl C=O bond
2-methylpropene The C=C bond
Butanone the carbonyl C=O bond
But-2-ene The C=C bond (C-C=C-C)
2-methylpropene the C=C bond
