Frage 2

Alkanes are [blank_start]saturated[blank_end] molecules that are [blank_start]hydrocarbons[blank_end]; they only consist of [blank_start]carbon[blank_end] and [blank_start]hydrogen[blank_end] atoms. They can be formed as a product of the [blank_start]fractional distillation[blank_end] of [blank_start]crude[blank_end] oil, or by reacting an alkene with [blank_start]two[blank_end] hydrogen atoms. The first few alkanes - in ascending size order - are methane, [blank_start]eth[blank_end]ane, prop[blank_start]ane[blank_end], [blank_start]butane[blank_end], [blank_start]pentane[blank_end], and so on. From the fifth one, the [blank_start]prefix[blank_end] will refer to the number of [blank_start]carbon[blank_end] atoms it has, with 5 being "pent-", 7 being "sept-", 10 being [blank_start]"dec-"[blank_end], and so on. The suffix of any alkane will always be [blank_start]"-ane"[blank_end].
