Chemistry : Organic Chemistry – Some Basic Principles and Techniques

In cyclopropane, cyclobutane and cyclohexane, the common group is

• 

• 

• -CH₃

• 

CH₃CH₂OH and CH₃OCH₃ are the examples of

• chain isomerism

• functional isomerism

• position isomerism

• metamerism

In the following reaction

RCH₂COOH $\stackrel{{\mathrm{Br}}_2/ \mathrm{P}}{\to } \mathrm{X} \stackrel{\mathrm{excess} {\mathrm{NH}}_3}{\to }$ Y

The major maounts of X and Y are

• RCHBrCONH₂; RCH(NH₂)COOH

• RCHBrCOOH; RCH(NH₂)COOH

• RCH₂COBr; RCH₂COONH₄

• RCHBrCOOH; RCH₂CONH₂

Naphthalene can be easily purified by

• sublimation

• crystallisation

• distillation

• vaporisation

The monosaccharides having anomeric carbon atom are

• geometrical isomers

• α- and β- optical isomers

• having symmetrical carbon atoms

• None of the above

Which of the following will be easily nitrated?

• 

• 

• CH₃NO₂

• C₆H₅NO₂

In Kjeldahl's method of estimation of nitrogen, CuSO₄ acts as

• oxidising agent

• reducing agent

• catalytic agent

• hydrolysis agent

Example of geometrical isomerism is

• 2-butanol

• 2-butene

• butanal

• 2- butyne

A metal 'M' reacts with N₂ to give a compound 'A' (M₃N). 'A' on heating at high temperature gives back 'M' and 'A' on reacting with H₂O give a gas B. 'B' turns CuSO₄ solution blue on passing through it. M and B can be

• Al and NH₃

• Li and NH₃

• Na and NH₃

• Mg and NH₃

Electromeric effect is

• permanent effect

• temporary effect

• resonance effect

• inductive effect
