Question

which of the following requires least energy for vaporization
a) F2
b) Cl2
c) Br2
d) I2

little explain it​

Answer 1

Answer:

a) F2

Explanation:

Flourine is your answer as the standard enthalpy of vaporization for flourine is

6.62( approx).

In comparison,

Chlorine has 20.41(approx).

Bromine has 29.95(approx).

Iodine has 41.58(approx).

Answer 2

Answer:

F2

Explanation:

Specific heat of vaporization of F2 is 3.26 kilo joule per mol

Specific heat of vaporization of Cl2 is 10.2 KJ/mol

Specific heat of vaporization of Br2 is 15.438 KJ/mol

Specific heat of vaporization of I2 is 20.72 KJ/mol

So F2 has the least
