One of the following is a true statement: Select one:

1.Alkanes are the most unreactive group of compounds among functional groups I.

2.Alkanes undergo addition reaction with bromine/CC14 under vigorous conditions.

3.The properties, reactivity and colors of organic compounds depend on the type of their functional groups.

4.Alkanes, alkenes, alkynes and aromatics are all unsaturated compounds.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

the answer is b & c i believe : )

hope this contact me for more questions if you'd like: )
