Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: A solution of the product obtained by heating a mole of glycine with a mole of chlorine in presence of red phosphorous generates chiral carbon atom. Reason R: A molecule with 2 chiral carbons is always optically active.
In the light of above statements, choose the correct answer from the options given below:
- a✓
A is true but R is false
- b
Both A and R are true but R is the correct explanation of A
- c
A is false but R is true
- d
Both A and R are true but R is NOT the correct explanation of A
A is true but R is false
Strategy: Relate noble gas properties to their position in the periodic table.
Step 1: Trends As we go down the group, atomic radius increases, ionization enthalpy decreases, and boiling points increase due to stronger dispersion forces.
Step 2: Selection Matching the property trend to the specific noble gas atoms listed in the question leads to the answer.
