Correct Answer:
Option D i.e. CH3CH2CH2CH2CH3
Reason:
Isomers are the compounds having same molecular formula, but different structural formula.
The molecular formula of the compound is C5H12
The compound present is question (i.e. 2-methyl butane) and option D (n-pentane) has same molecular formula. Hence, they are isomers.However, compound present in option A, is the same compound provided in question. Hence, it is not an isomer. Compounds reported in option B and C has one carbon atom less and more, respectively as compared to the compound reported in question. Hence, they are also not isomers.
Answer:
number of protons =17
number of neutrons=20
number of electrons=17
Atomic number is the same as proton number
To find the neutrons
subtract the atomic number from the mass number
thus, Neutrons =Mass number - Atomic number
<em>Neut</em><em>rons</em><em>=</em><em>3</em><em>7</em><em>-</em><em>1</em><em>7</em>
<em>Neutr</em><em>ons</em><em>=</em><em>2</em><em>0</em>
