Question

The $\mathrm{LD}_{50}$ values (lethal dose in $\mathrm{mg} / \mathrm{kg},$ for rats) for the three organophosphorus insecticides listed in this section are parathion, $3-13 \mathrm{mg} / \mathrm{kg}$; diazinon, $250-285 \mathrm{mg} / \mathrm{kg} ;$ and malathion, $1000-1375 \mathrm{mg} / \mathrm{kg}$. (a) Find the molecular structures using the Internet. (b) Which would you choose for use in your garden and why? (c) Thinking about hydrophobic and hydrophilic, which is most dangerous for mammals to ingest? Why?
