    So sir water is always produced as vapour during combustion hence considered as a gas?

      Yes think about a car... Water comes out of the exhaust system in gas form

    Sir what does the exam guideline mean when it says Halogen substituents do not get preference over alkyl groups

    • @MlungisiNkosi
      @MlungisiNkosi  3 роки тому +1

      It means whether you don't place the halogen substituent first before the alkyl substituent if the letter of the alphabet does not come first
      Example if I have an - ethyl substituent and a fluoride halogen. I will put - ethyl before the - flouro when I name.

    Sir, for 2.3.3, Why did we not have to convert the cm cubed to dm cubed?

    • @MlungisiNkosi
      @MlungisiNkosi  3 роки тому

      You didn't need to because you did not have to use the c=n/V formula. All of your substances were in gaseous phase...
