(a) is used as a refrigerant for ice cream and frozen food.
(b) The structure of contains twelve six-membered carbon rings and twenty-five membered carbon rings.
(c) , a type of zeolite, is used to convert alcohols into gasoline.
(d) is a colourless and odourless gas.
(a) is used as a refrigerant for ice cream and frozen food.
(b) The structure of contains twelve six-membered carbon rings and twenty-five membered carbon rings.
(c) , a type of zeolite, is used to convert alcohols into gasoline.
(d) is a colourless and odourless gas.
- A(a) and (c) only
- B(b) and (c) only
- Correct answerC(c) and (d) only
- D(a), (b) and (c) only
Solution
(1) \(\mathrm{CO}_2\) (s) (dry ice) [not \(\left.\mathrm{CO}_2(\mathrm{~g})\right]\) is used as refrigerant for ice cream and frozen food.
(2) The structure of \(\mathrm{C}_{60}\) contains 20 six carbon rings and 12 five carbon rings.
(3) ZSM-5 (a type of zeolite) is used to convert alcohols directly into gasoline.
(4) \(\mathrm{CO}(\mathrm{g})\) is colourless and adourless gas
Hence, the correct answer is option: 'C'.
