Organic chemistry is the study of carbon-based compounds. pH measures acidity or alkalinity. TLC is a technique for separating compounds.

• Organic chemistry focuses on the study of carbon-containing compounds.

• pH is a measure of the acidity or alkalinity of a solution.

• TLC (Thin Layer Chromatography) is a technique used to separate and analyze compounds in a mixture.

• Polar solvents dissolve polar compounds, while non-polar ...read more

AA is a common abbreviation for amino acids. They have a general structure of NH2-CHR-COOH and can undergo various named reactions like Grignard reaction.

• AA stands for amino acids which are the building blocks of proteins

• Their general structure is NH2-CHR-COOH where R can be any of the 20 different side chains

• Grignard reaction is a named reaction used to form carbon-carbon bonds and is commonly used in organic synthesi

Density of solvents is an important property for various chemical processes.

• Density is the mass per unit volume of a substance.

• Solvents with higher density can dissolve more solutes.

• Density can be affected by temperature and pressure.

• Examples of solvents with different densities include water (1 g/mL), ethanol (0.789 g/mL), and chloroform (1.48 g/mL).

KF R factor analysis is performed by calculating the ratio of the observed variance to the expected variance in a factor analysis model.

• Calculate the ratio of the observed variance to the expected variance for each factor in the factor analysis model.

• The KF R factor analysis helps in determining the goodness of fit of the factor model.

• Higher KF R values indicate a better fit between the observed data and the factor mod

A polarimeter is a scientific instrument used to measure the angle of rotation of polarized light as it passes through a substance.

• Polarimeters are commonly used in chemistry to determine the concentration and purity of optically active substances.

• The principle of a polarimeter is based on the ability of chiral molecules to rotate the plane of polarized light.

• The angle of rotation is measured using a polarizer, a polar...read more

The principal UV-visible spectrophotometer is a scientific instrument used to measure the absorption of light by a sample in the ultraviolet and visible regions of the electromagnetic spectrum.

• UV-visible spectrophotometers are commonly used in analytical chemistry, biochemistry, and pharmaceutical industries.

• They are used to determine the concentration of a sample by measuring how much light it absorbs at different wav...read more
