MCQ
Compound having the some molecular formula but different structural formula are known as isomers which of the following statement is correct with respect to isomerism.
P : Main cause of isomerism is the difference in the mode of linking of atom & different arrangement of atom.
Q: Isomers have same physical and chemical property.
  • A
    Only P
  • B
    Only Q
  • C
    Neither P nor Q
  • D
    Both P and R
✓

Answer

(a) Only P
Explanation : $C _4 H _{10} O$ show different linkages and form three different types of ether.
$C _2 H _5- O - C _2 H _5, CH _3- OC _3 H _7, CH _3- O - CH \left( CH _3\right)_2$ while difference in the arrangement of atom is steroisomerism for eg. 1,2 dichloroethene

Isomers have different physical property &  chemical property. For e.g. the isomers of $C _2 H _6 O$ are $C _2 H _5 OH$ and $CH _3- O - CH _3$. The former is alcohol and later is ether hence they may differ in properties.
