Sample questions
-
1.Assertion (A): The carbon-halogen bond of an alkyl halide is polarised with carbon bearing a partial positive charge. Reason (R): Halogen atoms are more electronegative than carbon.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
2.DDT (p,p'-dichlorodiphenyltrichloroethane) is best described as:
- A.the first chlorinated organic insecticide, effective against malarial mosquitoes
- B.a refrigerant gas
- C.a general anaesthetic
- D.an antiseptic releasing free iodine
-
3.A mixture containing two enantiomers in equal proportions is called a racemic mixture. Its net optical rotation is:
- A.zero
- B.double that of either enantiomer
- C.always strongly dextrorotatory
- D.always strongly laevorotatory
-
4.Which of the following is correctly classified as a tertiary (3 degree) alkyl halide?
- A.2-Bromo-2-methylbutane, (CH3)2CBrCH2CH3
- B.1-Bromopentane, CH3CH2CH2CH2CH2Br
- C.2-Bromopentane, CH3CH2CH2CH(Br)CH3
- D.1-Bromo-2,2-dimethylpropane, (CH3)3CCH2Br
-
5.Assertion (A): SN2 reactions of optically active alkyl halides are accompanied by inversion of configuration. Reason (R): The nucleophile attacks the carbon from the side opposite to the leaving halogen atom.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
