Question

alkyl I) Which of the following best describes the carbon-chlorine bond of an alkyl chloride? A) nonpolar; no dipole B) polar; d at carbon and d- at chlorine C) polar: d- at carbon and d+ at chlorine ionic E) none of the above 2) What general classification is given to the molecule below? CI A) primary chloride B) secondary chloride C) tertiary chloride D) vinyl chloride E) benzyl chloride 3) Which of the following is a secondary halide? A) ClCH2CH2C (CH303 BO CICH2CH2CHOCH302 C) (CH3)2CCICH2CH3 D (CH3)3CCHCICH3 E) CICH2C(CH3)CH2CH3 4) Which of the following is a geminal dihalide? A) cis-1,2-dibromocyclopentane B) 3,3-dichloropentane C) trans-1,4-diiodocyclohexane D) isobutyl chloride E) 1,3-dibromoheptane

Explanation / Answer

(1) (B) Polar, partial positive sign on C and partial negative sign on X, due to more electronegativity of X than C

(2) (C) Tertiary chloride, because Cl containing carbon is attached to 3 other carbons.

(3) (D) Because Cl containing carbon is futher attached to 2 other carbons.

(4) (B) presence of halogen atom on same carbons is called gem dihalide

(5) (A) Methylbromide. Because Br containing carbon is attached to 3 hydrogens or 2 hydrogens and 1 carbon.

(6) (D)

(7) (B) vicinal and aryl
