O, ROH are examples of Lewis bases

Question 6. Assertion(A): SiF_cuatro can act as Lewis acid. Reason (R): In SiF₄, the central atom can expand its octet due to the availability of empty d – orbitais and can accept a pair of electrons. (a) Both A and R are correct and R is the correct explanation of A (b) Both A and R are wrong (c) A is correct but R is wrong (d) A is wrong but R is correct Answer: (a) Both A and R are correct and R is the correct explanation of A

Reason (R): It is because popular ion impact

Question 7. Assertion(A): NH_{step step step three}, H₂ Reason (R): Molecules with one or more lone pairs of electrons act as Lewis bases. (a) Both A and R are wrong (b) A is correct and R is the correct explanation of A. (c) A is wrong but R is correct. (d) A is correct but R is wrong Answer: (b) A is correct and R is the correct explanation of A.

Assertion(A): To your escalation in temperatures, the fresh ionic device out-of liquid including increases

Matter 8. Assertlon(A): HCl is an enthusiastic solid acid while you are HCOOH try a failure acid. Reason (R): HCI is wholly ionised within the water while HCOOH was paritally ionised within the water. (a) One another A and you will Roentgen try wrong (b) Good are wrong however, Roentgen is right (c) Good is correct but R is completely wrong (d) One another A beneficial and you will Roentgen was proper and R ‘s the proper reasons regarding Good Respond to: (d) Both An effective and you may Roentgen try right and you can R ‘s the correct explanation regarding Good

Question nine. Cause (R): This new dissociation out-of liquids try a keen endothermic impulse. (a) Each other A beneficial and you will Roentgen try proper and you can R is the correct need of An excellent (b) A beneficial is correct however, Roentgen was completely wrong (c) A good try completely wrong however, R is right (d) Both A good and you may Roentgen is completely wrong Answer: (a) Each other An effective and you may Roentgen is proper and you may Roentgen ‘s the correct need regarding A good

Question 10. Assertion(A): Whenever dilution increases, the amount of dissociation of weakened electrolyte including grows. Cause (R): The level of dissociation a is actually inversely proportional so you’re able to amount c. When the dilution develops by the a hundred times, the latest dissociation develops from the ten moments. (a) Each other An effective and you can R are correct and you can Roentgen ‘s the best reason from A beneficial (b) One another A and you can R was incorrect (c) A is right but Roentgen was wrong (d) An effective is wrong however, R is correct Answer: (a) Both Good and you will Roentgen are proper and you will R is the best explanation out-of Good

Question 11. Assertion(A): The addition of sodium acetate to acetic acid solution leads to the suppression in the dissociation of acetic acid. i.e., CH₃COOH and CH₃COONa both contains CH₃COO – ion as common. (a) Both A and R are correct and R is the correct explanation of A (b) BothA and R are wrong (c) A is correct but R is wrong (d) A is wrong but R is correct Answer: (a) Both A and R are correct and Lansing escort service R is the correct explanation of A

Question 12. Assertion(A): The solution of NH₄CI has pH value less than 7. Reason (R): The salt of weak base (NH₄OH) and strong acid (HCl) is acidic in nature, when dissolved in water. So pH value is less than 7. (a) Both A and R are correct and R is the correct explanation of A (b) Both A and R are wrong (c) A is correct but R is wrong (d) A is wrong but R is correct Answer: (a) Both A and R are correct and R is the correct explanation of A
