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.
Definitely, the correct answer is option B. When Ca(OH)2 is added into a beaker, the solution will turn into pink when the indicator phenolphthalein is added. This is due to the hydroxide ions from the calcium hydroxide dissolved in water. The compound dissociates into calcium ions and hydroxide ions.
Zn (Zinc) is metal
Ne (Neon) is nonmetal
Mg (Magnesium) is metal
Fe (Iron) is metal
Cl (Chlorine) is nonmetal
