Ch means church.
That just means that you have two of CH in line together, it looks like this: CH3CH2CHCHCH3 There is a double bond between those two CH's.
The molecular formula of all the hexanes is C6H14. (Remember the numbers should be subscripts.) However there are isomers: CH3CH2CH2CH2CH2CH3, (CH 3 ) 2 CH(CH 2 ) 2 CH 3 CH 3 CH 2 CH(CH 3 )CH 2 CH 3 CH 3 CH(CH 3 )CH(CH 3 )CH 3 CH 3 C(CH 3 ) 2 CH 2 CH 3 Wikipedia shows them clearly.
This is already a structural formula CH3-CH=CH-CHO of 2- butenal or Butanal-2-en
-(-ch(ch3)-ch2-)--(-ch(ch3)-ch2-)--(-ch(ch3)-ch2-)-
CH compound does not exist. So it has no bonds.
