Assertion (A): Solvay process is used for the preparation of NaHCO3 but not for KHCO3
Reason (R): Solubility of KHCO3 is more than NaHCO3 in water
A and R are true and R is the correct explanation of A
A and R are true and R is not the correct explanation of A
A is true, R is false
Both A and R are false
Assertion (A): Sodium metal is stored in kerosene
Reason (R): The density of sodium is less than water
(a) Both Assertion (A) and Reason (R) are true and Reason (A) and Reason (R). For selecting the correct answer, use the following code :
(b) Both Assertion (A) and Reason (R) are true but Reason (R) is not a correct explanation of Assertion (A).
(c) Assertion (A) is true and Reason (R) is false.
(d) Assertion (A) is false and Reason (R) is true.
Assertion (A) Reason (R)√3 is an irrational number. The sum of a rational numberand an irrational number is anirrational number.The correct answer is: (a)/(b)/(c)/(d).
This question consists of two statements, namely, Assertion (A) and Reason (R). For selecting the correct answer, use the following code:
(a) Both Assertion (A) and Reason (R) are true and Reason (R) correct explanation of Assertion (A).
Assertion (A): Electrophilic substitution reactions takes place in phenol than in nitro benzene
Reason (R): Hydrogen bonding is present in phenol but not in nitrobenzene
