TM H Show the synthetic sequence that converts acetylene to the target molecule (TM) shown below.

Draw the major substitution products you would expect for the reaction shown below. If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used. A Cl •|||| to H₂O + X Click and drag to start drawing a structure.

Provide the structure of the 1,4 addition product for the reaction of 1,3-hexadiene with Br2/CCl4. Help please!

For this mechanism, how come the iodine doesn't attach to a carbocation on the right (with the two methyl groups coming off of it)? Is it because TsO is a better leaving group? If so, why is this?
