Vedclass · Answer

(D) The primary alcohols ($1^\circ$ alcohols) with the molecular formula $C_5H_{12}O$ are derived from the pentyl group attached to an $-OH$ group.$1$. $CH_3-CH_2-CH_2-CH_2-CH_2OH$ (Pentane$-1-$ol)$2$. $CH_3-CH_2-CH(CH_3)-CH_2OH$ ($2$-Methylbutan$-1-$ol). This molecule has a chiral center, so it exists as two enantiomers ($R$ and $S$).$3$. $CH_3-CH(CH_3)-CH_2-CH_2OH$ ($3$-Methylbutan$-1-$ol)$4$. $(CH_3)_3C-CH_2OH$ ($2$,$2$-Dimethylpropan$-1-$ol)Counting the stereoisomers for $2$-methylbutan$-1-$ol, we have: $(1)$ Pentane$-1-$ol, $(2)$ $(R)$$-2$-methylbutan$-1-$ol, $(3)$ $(S)$$-2$-methylbutan$-1-$ol, $(4)$ $3$-methylbutan$-1-$ol, and $(5)$ $2,2$-dimethylpropan$-1-$ol.Thus, there are $5$ primary alcohols possible.

How many primary alcohols (including stereoisomers) are possible with formula $C_5H_{12}O$?
