How many structural isomers can you draw for pentane?
three structural isomers Pentane has three structural isomers that are n-pentane, Iso-pentane (methyl butane) and neopentane (dimethylpropane). Therefore three structural isomers can be drawn from pentane.

A buffer solution containing `0.25mol//L` of `NH_(4)CI` and `0.05mol//L` of `NH_(4)OH` is in equilibrium with `A1^(+3)` and `Mg^(2+)` ions. Calculate
B. Not all the sulphide which dissolves remains as `S^(2-)`, most of it hydrolyses: `S^(2-) +H_(2)O hArr HS^(Θ) + overset(Θ)OH`.
