1A - Basic concepts review

    1)           What do we mean by a saturated hydrocarbon?  [2]

                    Contains only hydrogen and carbon [1] all C - C bonds are single bonds

    2)          Give the general formula for the alkenes [1]  C_nH₂n

    3)          Draw the displayed formula of 2 - methyl propan-2-ol [2]

    4)           Name the following molecule:  [1]  3 methyl pentanal

    5)           Calculate the molecular formula of a hydrocarbon that contains 1.2g of C, 0.250g of H and

                  has an Mr = 58  [3] 

                      Moles C = 0.1  :  H = 0.25 [1]  Ef = C₂H₅ [1]  Mf = C₄H₁₀  [1]

    6)           Draw the structural formula for  [1]  CH₃CH₂CH(CH₃)CH₂CO₂H

                                Correct molecule drawn [1]  drawn displayed  [1]

    10)         Define stereoisomerism [1]

                   Same structural formula, different spatial arrangement of atoms
