if you could help me with all these questions itd be greatly appreciated!

12.14 There are three compounds with the molecular formula C2H2Br2. Two of these are polar and have a dipole, and one has no dipole (it is not polar). Draw structural formulas for these three compounds and explain why two are polar and the third is not. 12.22 Draw a structural formula for each compound. (a) trans-2-Methyl-3-hexene (b) 2-Methyl-3-hexyne (c) 2-Methyl-1-butene (d) 3-Ethyl-3-methyl-1-pentyne (e) 2,3-Dimethyl-2-pentene 12.24 Write the IUPAC name for each unsaturated 12.26 Explain why each name is incorrect and then write a correct name. (a) 1-Methylpropene (b) 3-Pentene (c) 2-Methylcyclohexene (d) 3,3-Dimethylpentene (p) 4-Hpyyne (f) 2-Isopropyl-2-butene 12.30 Which of these alkenes shows cis-trans isomerism? For each that does, draw structural formulas for both isomers. (a) 1-Pentene (b) 2-Pentene (c) 3-Ethyl-2-pentene (d) 2,3-Dimethyl-2-pentene (e) 2-Methyl-2-pentene (f) 2,4-Dimethyl-2-pentene 2.32 Arachidonic acid is a naturally occurring polyunsaturated fatty acid. Draw a line-angle formula for arachidonic acid showing the cis configuration about each double bond. CH3(CH2)4(CH=CHCH2)4CH2CH2COOH
