In a rainforest food chain, caterpillars and butterflies eat orchid plants. Toucans eat the caterpillars and butterflies. Leopards eat the toucans.

Which statement describes the energy in this food chain?

The leopards gain energy directly from the butterflies.
The orchids have the least amount of available energy.
The caterpillars gain energy directly from the orchids.
The toucans have more available energy than the butterflies.

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
