Answer:

Here's what I get.

Explanation:

(a) F, Cl, Br, and I are called halogens (salt formers)

(i) They are placed in Group 17, the Group just before Group 18 (the noble gases), because they need just one more valence electron to get a noble gas electron configuration.

(ii) At room temperature, iodine is a lustrous, purple-black solid that melts to form a deep violet liquid at 114 °C.

Assuming the relative rate of secondary hydrogen atom abstraction for the chlorination of propane is 3.9 times faster than the r
Ghella [55]

Answer:

% of n-propyl chloride = 43.48 %

Explanation:

There are 2 secondary hydrogens and 6 primary hydrogens

The rate of abstraction of seondary hydrogen = 3.9 X rate of abstraction of primary hydrogen

probability of formation of isopropyl chloride = 3.9 X 1 (relative rate X relative number of secondary hydrogens)

Probability of formation of n-propyl chloride = 1 X 3 (relative rate X relative number of primary hydrogens)

Total probability = 3.9

% of n-propyl chloride = 3 X 100 / 6.9 = 43.48 %
