For the given alkyne, determine the product(s) when it undergoes halogenation reaction (with 1 equiv. Br 2).
For the given alkyne, draw the product(s) when it undergoes a reaction with Cl 2 (2 equiv.).
For the addition of Br2 and Cl2 to alkynes, trans addition is highly favored. However, more of the syn addition product is produced with chlorination. Justify this fact.
Determine the major product when the Br2 (2 mol)/CH2Cl2 reagent reacts with 3-hexyne.
Determine the major product when the Br2 (2 mol)/CH2Cl2 reagent reacts with 2-pentyne.
Determine the major product formed in a reaction between hex-3-yne and 1 eq. of Br 2 in CH2Cl2.
Determine the major product formed in a reaction between pent-2-yne and 1 eq. of Br 2 in CH2Cl2.
