An alkyne with the molecular formula C5H8 was reduced with H2 and Lindlar's catalyst. Hydroboration-oxidation of the resulting a
irinina [24]

Since the addition of the H2O in the last step of hydroboration is anti-Markovnikov, the starting material is 1-pentyne.

The addition of H2 to C5H8 yields an alkene when a Lindlar catalyst is used. Recall that the Lindlar catalysts poisons the process so that the addition do not go on to produce an alkane.

When hydroboration is carried out on the alkene, we are told that a primary alcohol was obtained. We must note that in the last step of hydroboration, water is added in an anti- Markovnikov manner to yield the primary alcohol. Hence, the starting material must be 1-pentyne as shown in the image attached.

hich of the following is best described as a decomposition reaction? HCl + NaHCO3 → H2O + CO2 + NaCl 2Na + Cl2 → 2NaCl 2HgO → 2H
sp2606 [1]

Answer:

The answer to your question is: c

Explanation:

A descomposition reaction is a chemical reaction in which the only one reactant yields two or more products.

a) HCl + NaHCO3 → H2O + CO2 + NaCl

This is not a descomposition reaction because there are two reactants not one, this option is incorrect.

b) 2Na + Cl2 → 2NaCl

THis option is also incorrect because there are two reactants in descompositin reaction there is only one reactant.

c) 2HgO → 2Hg + O2

There are only one reactant that yields 2 products, this is a descomposition reaction.

d) AgNO3 + NaCl → AgCl + NaNO3

THis is not a descomposition reaction because there are two reactants.
