please answer it correctly thank you

1) Draw the expanded structural diagrams for the following (this means you need to show all the hydrogens): (12 marks - C) a) octane b) 3-ethyl-2-methyl nonene c) 3-heptyne d) 3,3-dimethyl pentane e) 2-methyl-2-butene f) 4-methyl-2-pentyne 2) Name the following: (12 marks-C) a) H-C H C-H H CH3-CH3-C 5C -CH2-CHE b) c) CHE CH-CH2-C =C -CH-CH2-CH-CH2 - CHE , CHE d) CH3-CHE HC-CH2-CH-CH3-CH3 e) CH3-CH2-CH=CH-CH2-CH3 H2-CH=C=C-CH=CH-CH CHE CH-CH f) 3) Draw the complete combustion reaction for 2-butene below. You need to draw out 2- butene, do not just write the formula. You do not need to balance. (2 marks - A)
