Question

The total number of all structural isomers of molecular formula $C_4{H}_{10}O$ will be

• A. 5
• B. 6
• C. 7
• D. 8

Answer 1

The correct option is C 7

• A structural isomer, also known as a constitutional isomer, is one in which two or more organic compounds have the same molecular formulas but different structures.
• There are three types of Structural isomerism existing namely chain isomerism, position isomerism, and functional group isomerism.
• There are seven isomers in $C_4{H}_{10}O$ . Out of these seven isomers, four are alcohol and three are ether.

Hence, option C is correct.
