Question 73 of 90 in this shift, Chemistry question 13 of 30, Section A.

Give below are two statements: Statement - I: Noble gases have very high boiling points. Statement - II: Noble gases are monoatomic gases. They are held together by strong dispersion forces. Because of this they are liquefied at very low temperature. Hence, they have very high boiling points. In the light of the above statements, choose the correct answer from the options given below:
  1. (1)Both Statement I and Statement II are true.
  2. (2)Both Statement I and Statement II are false.Official answer
  3. (3)Statement I is true but Statement II is false.
