Web18 C's are also solids. You can see that alkane boiling points increase with increasing molecular mass. For example, the boiling point of butane (C4H10) is about 0° C and each higher molecular mass alkane formed by adding a CH2 group to butane boils at a temperature ranging from 20° to 30° higher than the WebAug 28, 2024 · In group 15 the melting/boiling point increases up to Arsenic and then started decreasing. In groups 16, 17 and 18 it increases down the group, but with few exceptions. Groups 1 and 2 are held by metallic bonding and the strength of metallic bonding decreases down the group, so this explains the first two trends. Carbon doesn't …
