Rotenone, Azadirachtin are natural insecticides, synthetic routes are deveoped recently.
DDT, Gammaxene were used but were scraped out as they pose health hazards and are insects are able sustain the max. dosages every year. Generally, Semio-chemicals, a class of compounds found in insects themselves are being studied and used as effective insecticides and warfare agents.
Answer :
- Monounsaturated fat: This is a type of fat found in a variety of foods and oils.
- Polyunsaturated fat: This is a type of fat found in plant-based foods and oils.They can be divided into two groups known as omega-3 fats and omega-6 fats.
- Omega-3 fatty acids: One type of polyunsaturated fat made up of mainly omega-3 fatty acids and may be beneficial to heart.
- Omega-6 fats decrease risk of heart disease when they are consumed in place of saturated and trans fats.
Analytical Chemistry Interview Questions Answer :
IN coordinate covalent bond electrons which are shared by both the atoms are comtributed by only one atom . This is otherwise known as dative bond.
In covalent bond the electrons shared by both the atoms are contributed by both the atoms equally.
Answer :
when alcohols reats with aminoacids esters are formed. The esters are volatile in contrast to free aminoacids.
R-CH-COOH + H2O-C2H5 -> R-CH-COO-C2H5 + H2O

Chemical Interview QuestionsAnswer :
Geometrical isomerism is an example of stereo-isomerism.
This occurs when substances have the same molecular formula, but a different arrangment of their atoms in space. There are three ways that this can happen:
where there is a C=C bond in the molecule;
where a molecule has rings; or
where there is a >C=N bond.Answer :
Proteins are precipitated from aqueous solution by high concentrations of neutral salts. This is the'salting -out' process.

Answer :
An ion is a specie that have no unpaired electron and is charged, either positively or negatively i.e. may be a cation or an anion. It is formed due to heterolysis of a molecule
e.g HCl----> H+ + Cl-
A radical is a neutral specie having atleast one unpaired electron and is formed due to homolysis of a molecule
e.g H-H -------> H* + H*
The * shows an unpaired electron. Similarly CH3* is a radical.
