What is the structural formula of malathion,parathion?
To find the structural formulas of malathion and parathion, we need to understand their chemical structures and how they are named.
1. Malathion:
Malathion is an organophosphorus compound used as an insecticide. Its structural formula is as follows:
CH3
|
O
//
P-O
\\
S
//
H-O-C-CH2-O-CH2-CO-OCH3
In this structure, the central phosphorus atom (P) is bonded to an oxygen atom (O). The phosphorus atom is also bonded to two sulfur atoms (S), with a double bond to one sulfur, forming a P=S bond. One of the sulfur atoms is bonded to an oxygen atom (O) and another oxygen atom (O) is bonded to the carbon (C) through an ester linkage (O=C-O-CH3). The remaining carbon (C) is bonded to a methyl group (CH3).
2. Parathion:
Parathion is also an organophosphorus compound used as an insecticide. Its structural formula can be represented as follows:
H H
| |
H-C-C-C-O-P
||
O-CH3
In this structure, there is a central phosphorus atom (P) bonded to two oxygen atoms (O). The phosphorus atom is also bonded to three carbon atoms (C) in a linear fashion. Two of the carbon atoms (C) are bonded to hydrogen atoms (H), and the other carbon atom (C) is bonded to an oxygen atom (O) through a double bond. This oxygen atom (O) is further bonded to a methyl group (CH3).
