An alkyne of six carbon atoms gives the same single product in its reaction either with bh3 in thf followed by h2o2 / oh-, or with h2o/hg2 / h3o. draw the structure of the alkyne (containing only carbon and hydrogen atoms).

Two compounds containing six carbon atoms on treatment with either with BH ₃ in THF followed by H ₂ O ₂ / OH ⁻ (OR) with H ₂O / Hg ²⁺ / H ₃O⁺ gives the same products.

The two alkynes, their two different types of reactons and products are given below,
