Question

(e) h₃c—hc—ch₂—o—ch₃
ch₃
amine
ketone
alkane
alcohol
ether
ester
carboxylic acid
alkene
aromatic
alkyne
aldehyde

Explanation:

• An amine has an -NH₂, -NH-, or -N- group. This compound has no nitrogen, so it's not an amine.
• A ketone has a -CO- group (carbonyl between two carbons). No such group here.
• An alkane has only C - C and C - H single bonds. This has an oxygen - containing functional group.
• An alcohol has an -OH group. No -OH here.
• An ether has an -O- group (R - O - R'). Here, we have \(CH_3 - CH(CH_3)-CH_2 - O - CH_3\), which fits the R - O - R' (ether) structure.
• An ester has a -COO- group. No such group.
• A carboxylic acid has a -COOH group. No.
• An alkene has a C = C double bond. No.
• An aromatic compound has a benzene - like ring. No.
• An alkyne has a C ≡ C triple bond. No.
• An aldehyde has a -CHO group. No.

Answer:

ether
