Show how to synthesize 2-methyl-2-pentene from an alkyl halide and an aldehyde or ketone, plus any other necessary reagents.
Then show the reagents necessary to convert butyraldehyde into the following. There may be one more step:
A.) 1-phenyl-1-pentene
B.) CH3CH2CH2CH2NHCH3
C.) CH3CH2CH2CH2-O-CH2CH3
