✔ 最佳答案
甲烷 should be CH4 !1. CH4 methane has the HIGHEST boiling point -> -182 d.c.
CO b.p. = -192 d.c.
N2 b.p. = -196 d.c.
H2 b.p. = -252 d.c.
2. N2 is almost an inert gas
while CH4, H2 AND CO are all combustible
3. CH4 is organic
although CO contains carbon constituents, it is NOT an organic compund!
