NEET Solved Paper 2018 Question 35
Question: Among $ Ca{H_2} $ , $ Be{H_2} $ , $ Ba{H_2} $ , the order of ionic character is [NEET - 2018]
Options:
A) $ Be{H_2} <\text { Ba}{H_2} < \text{ Ca}{H_2} $
B) $ Ca{H_2}< \text { Be}{H_2} <\text{ Ba}{H_2} $
C) $ Be{H_2} <\text{ Ca}{H_2} <\text{ Ba}{H_2} $
D) $ Ba{H_2} <\text{ Be}{H_2} <\text{ Ca}{H_2} $
Show Answer
Answer:
Correct Answer: C
Solution:
- The correct option is C $ Be{H_2} <\text{ Ca}{H_2} <\text{ Ba}{H_2} $ For 2nd group hydrides, on moving down the group metallic character of metals increases so the ionic character of metal hydride increases. Hence option (c) should be the correct option.
