Question

True or False The relative acidities of two acids can be predicted by comparing their boiling points a. b. Molecule A has more bond dipoles than Molecule B. Therefore Molecule A must be more polar than Molecule B. c. The R enantiomer of a particular chiral compound will rotate plane polarized light in the clockwise direction. d. Specific rotation depends on wavelength, path length, and temperature. e. A mixture of two enantiomers is called a racemic mixture. f. Racemic mixtures do not rotate plane polarized light g. BH is a Lewis acid. h. Organic chemistry is challenging but awesome

Explanation / Answer

(a) True, you can compare two acids with their boiling points.

(b) True, bond diploe depends upon the polarity.

(c) True, since R comes in dextrorotatory part so, it will rotate the plane polarized light in the clockwise direction.

(d) True, specific rotation depends upon the wavelength, path length, and temperature.

(e) True, a mixture of two enantiomers is called as a racemic mixture.  

(f) True, racemic mixtures will not rotate the plane-polarized light.

(g) True, BH3 is a Lewis acid because it can accept a lone pair of electrons.

(h) True, organic chemistry is challenging but it is always awesome.
