From the given set of statement/data :
(A) Normal boiling point means boiling point at 1 atm pressure
(B) Standard boiling point means boiling point at 1 bar pressure
(C) At (\mathrm{STP}\left(0^{{}^{\circ}} \mathrm{C}\right.) and 1 bar pressure) molar volume is 22.4 L of an ideal gas
(D) At SATP (\left(25^{{}^{\circ}} \mathrm{C}\right.) and 1 bar pressure) molar volume is 22.4 L of an ideal gas
The correct statement is :
Options
- AA only
- BD only
- CB, C and D only
- DA, B and C only
Correct answer
D. A, B and C only
Step-by-step solution
- (A) is correct: Normal boiling point refers to the boiling point of a liquid at 1 atm pressure.
(B) is correct: Standard boiling point refers to the boiling point at 1 bar pressure.
(C) is correct: At STP ((0^{\circ} \mathrm{C}) and 1 bar), the molar volume of an ideal gas is approximately 22.4 L.
(D) is incorrect: At SATP (\left(25^{\circ} \mathrm{C}\right.) and 1 bar), the molar volume of an ideal gas is approximately 24.789 L, not 22.4 L.
Hence, only A, B, and C are correct.
