Question

Which of the following saturated compounds contains an alcohol group?

C4H10O
C4H8O
C3H6O
C4H9ONa​

Answer 1

Answer:

c4H10o

Explanation:

alchohal formula= cnh2n+2o

Answer 2

C4H10O is the chemical formula of butanol, which is an alcohol (option 1).

• For an alcohol or hydroxyl group (-OH) to attached to a saturated compound, it should first get converted to alkyl form. This happens by the loss of one hydrogen atom from the alkane. For example, CH4 (methane) loses a hydrogen atom to form CH3 (methyl).
• The alkyl form of the alkane is highly reactive and gets associated with a functional group easily. When it is associated with a hydroxyl group (-OH), it becomes an alcohol.
• C4H10 is the chemical formula of butane. By losing one hydrogen atom it becomes butyl (C4H9). This compound attaches to a hydroxyl group to give C4H9OH. This compound is butanol and same as C4H10O.
