Ch means church.
The "ch" in "temp" most likely stands for "channel," where it refers to the designated channel or frequency used for transmitting and receiving data or signals in a communication system or device.
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.
4-Isopropyldecane is a branched alkane with a total of 10 carbon atoms. The main chain consists of a straight chain of 10 carbon atoms (decane), with an isopropyl group (-C(CH₃)₂) attached to the fourth carbon of the chain. The molecular formula for 4-isopropyldecane is C₁₀H₂₁. The structure can be represented as follows: CH₃-CH₂-CH(CH₃)₂-CH₂-CH₂-CH₂-CH₂-CH₃, indicating the position of the isopropyl group on the fourth carbon.
The statement char ch = 'z'; would store the character 'z' in the variable ch. This means that the variable ch would hold the value 'z'.
CH compound does not exist. So it has no bonds.
