This is because the p-orbital of the halogen atom can enter into the delocalised π- electrons of the benzene ring. ]]> 2019-01-30 12:12:16 UTC https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794929 hol_cjones https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794930 Electrophilic Substitution]]> 2019-01-30 12:12:16 UTC https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794930 hol_cjones https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794931 Electrophilic Substitution]]> 2019-01-30 12:12:16 UTC https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794931 hol_cjones https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794932 Electrophilic Substitution]]> 2019-01-30 12:12:16 UTC https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794932 hol_cjones https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794933 Electrophilic Substitution]]> 2019-01-30 12:12:17 UTC https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794933 hol_cjones https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794934 2019-01-30 12:12:17 UTC https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794934 hol_cjones https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794935 2019-01-30 12:12:17 UTC https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794935 hol_cjones https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794937 X-ray diffraction studies give us data on the bond lengths and angles.
The carbon-carbon bonds in benzene exist as a hybrid between a single and a double bond. All of these bonds are equivalent.
The atoms making up benzene are all placed in one plane, making the molecule flat/planar.
The fact that all bond lengths are the same indicate no single or double bonds.]]> 2019-01-30 12:12:17 UTC https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794937 hol_cjones https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794938 2019-01-30 12:12:17 UTC https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794938 hol_cjones https://padlet.com/hol_cjones/o15gam99pmyb/wish/325794939 If we add more that one type of functional group to our root compound (benzene or a straight chain) then we need to know which addition is the principle group.
The principle group is names using its suffix.
