The diagram shows the structural formula of an organic compound.

Which statement about this compound is correct?

A​​ It is a saturated hydrocarbon.

B​​ It is an alkene.

C​​ It is an isomer of butane.

D​​ It will undergo addition with hydrogen

 

Answer: ​​​​ A

Explaination

This is the structure of saturated HC, contains C-C single bond and C-H single bond. There are 4C atoms and 8H atoms (instead of 10H atoms) with the depletion of 2H atoms to form cycloalkane. Its not an isomer of butane as butane contains 4C atoms and 10H atoms. Its not alkene because there is no C=C double bond and at last addition reaction comes under alkene reactions not in alkane chemical reactions.​​
