Interpretation Introduction

Interpretation:

The two commonly used compounds in weed killers should be identified and they should be compared in terms of types of plants they killed.

Concept Introduction:

Weed killers are generally known as herbicides, they are chemical substances used to kill weeds which are unwanted plants. They are of two types: selective and non-selective. Selective herbicides kill specific weed species and do not harm others, but non-specific herbicides are total weed killers and kill all plant materials. The selective herbicides only kill specific weed species this may be due to translocation and physical or physiological difference of the plant species.

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments. This especially applies to the reactions in…
