Question

which is the incorrect statement? a)open chain compounds are called alipatic compunds b)unsaturated compunds contain multiple bonds in them c)syturated hydrocarbon are called alkenes d)aromatic compunds process a characteristic aroma​

Answer 1

Answer:

c

Explanation:

alkanes are saturated hydrocarbons

Answer 2

Alkenes are not saturated hydrocarbons. So the statement, (c) is false.

• Aliphatic compounds are organic compounds that do not obey Huckel's rule of aromaticity. They can be saturated, unsaturated, open-chain, or cyclic compounds. Generally, open-chain compounds are always aliphatic.
• Unsaturated compounds contain double and triple bonds, where the carbon undergoes $sp^{2}$, and $sp^{3}$ hybridization respectively to form multiple bonds.
• Aromatic compounds are the compounds that obey Huckel's rule of aromaticity, that is the presence of $4n+2$ π electrons. They possess a characteristic aroma and are hence termed aromatic compounds.
• The carbon in alkenes is $sp^{2}$ hybridized and forms a double bond with the adjacent carbon atom. So alkenes are unsaturated hydrocarbons.
