Answer: C. catenation and tetravalency allowing different arrangements
Q2. Which is the correct comparison of diamond and graphite?
- A.diamond conducts; graphite is hard
- B.diamond is hard and non-conducting; graphite is soft and conducting
- C.both are hard and non-conducting
- D.both are soft and conducting
Answer: B. diamond is hard and non-conducting; graphite is soft and conducting
Asked for the unknown; data is laid out in the stem. By hence answer = diamond is hard and non-conducting, graphite is soft and conducting. acids release H+ and have pH < 7. Putting it together option B) diamond is hard and non-conducting; graphite is soft and conducting. Others fail: option A) 'diamond conducts; graphite is hard' is incorrect: It is the reverse for both properties; option C) 'both are hard and non-conducting' doesn't hold - Graphite is soft and conducting.
Q3. Which allotrope of carbon is the best conductor of electricity?
- A.graphite
- B.diamond
- C.coal
- D.fullerene only
Answer: A. graphite
