Question
Fill in the blanks and or circle the correct bold word. The pKa of an alkyne is aboutwhile the pKa of an alkane is aboutHydrogenation of an alkyne can / cannot be controlled to give an alkene. Halogenation of alkanes with Cl_2 is more less selective than halogenation with Br_2 An alkyne is more / less acidic than an alkene because In anti / syn additions the new atoms add to the opposite faces of an alkene. An S_n2 reaction involves the collision of two alkyl halides to form a new carbon-carbon bond. Addition of two equivalents of HBr to an alkyne results in a vicinal / geminaldibromide.Explanation / Answer
a)25,51
b)can
c)more
d)alkyne is more acidic than alkene because of presence of sp carbon bonds which are more electronegative than sp2 bonds of alkene
e)anti
f)false
g)geminal
