I. Flee irons in atomic orbitals are involved in the breaking and forming of bonds II. Elements are converted from one to another III. Reaction rates are typically not affected by catalysts IV. Atoms are rearranged by the breaking and forming of chemical bonds a. I and II b. I, II, and III c. III and IV d. II and III c. I, II, III, and IV Which one of the following changes would alter the rate constant (k) for the reaction 2A + B products? a. increasing the concentration of A b. increasing the concentration of B c. increasing the temperature d. measuring k again after the reaction has run for a while For which of the following species are the dispersion forces strongest? a. C_4H_10 b. C_5H_12 c. C_6H_14 d. C_7H_16 e. C_8H_18

Explanation / Answer

(43) Longest possible chain which includes more substituents is taken as parent chain.

Hence the IUPAC name of the compound is

d. 3 - methyl - 4 - propylheptane

(44) d. II and III

(45) Rate constant is only dependant on temperature. Hence,

c. Increasing the temperature.

(46) More is the molecular weight more is the strength of lodon force.

Hence,

d. C8H18
