Halogenoalkanes 5.0 / 5 based on 1 rating ? ChemistryHalgenoalkaneASOCR Created by: jammydodger29Created on: 10-03-14 18:29 What is a halogenoalkane? Halogenoalkanes are alkanes with halogen atoms 1 of 8 Describe one factor which influences the boiling points of halogenoalkanes The strength of the intermolecular forces (the stronger they are the higher the boiling point). 2 of 8 Describe the trend of the boiling points as you go down Group 7 The atom radius increases as you go down the group which mean the number of electron shells increases meaning you need more energy to overcome them. 3 of 8 What homologous series can be used to create halogenoalkanes? Alcohols 4 of 8 What is a nucleophile? Molecules with a pair of negative ions attracted to positive regions. Also have lone pairs such as O-H. 5 of 8 What is a carbocation? Ion with a positive carbon atom 6 of 8 Why is the carbon-halogen bond polar? The halogens are much more electronegative than carbon 7 of 8 What decides the reactivity of a halgenoalkane? The strength between the carbon-halogen bond. C-F is the strongest meaning any reaction involving this will take longer 8 of 8
