adding primary key constraint

A primary suffix is added to the word root (i.e., at the end of the word root) to indicate whether the parent chain is a saturated or unsaturated. Some primary suffixes are given below. Saturated - ane Unsaturated with: one double bond - ene two double bonds - ..

Mutual Induction - The phenomenon of production of induced emf in one coil due to change of current in a neighbouring coil is called mutual induction. Let us perform an experiment to understand this. Place two coils P and S close to each other as shown here Connect a battery and a key to ..

Aliphatic cyclic compounds are called alicyclic compounds. These compounds are named as follows: The number of carbon atoms in the ring determines the word root. The primary suffix cyclo- is added before the word root. The primary suffix is determined by the nature of ..

Mutual Inductance - We know that if a current builds up or varies in a coil, the flux change leads to induced e.m.f in the same coil. This can happen event mutually between two interacting coils are close together, and if current is passed in one of them, it sets up a magnetic flux surrounding itse..

Amines are formed by replacing one or more hydrogen atoms of ammonia (NH 3 ) with alkyl groups. These are further classified as primary, secondary and tertiary amines according to one, two or three hydrogen atoms of ammonia being replaced by alkyl groups. For example, Primary (a..

It is the result of the activity of the vascular cambium, which occurs in between xylem, and phloem of each vascular bundle. Hence, it is also known as intra-fascicular cambium. In addition, towards the beginning of secondary growth there is a process of dedifferentiation in some of the parenchyma ..

Acyl halides are reduced to primary alcohols with LiAlH 4 and NaBH 4 . Partial reduction of acyl chloride to aldehydes can also be done by catalytic hydrogenation over palladium catalyst supported on barium sulphate. Small accounts of quinoline and sulphur are added to the react..

. So there is no acidic hydrogen to react with alkali added. Hence it is insoluble in alkal..

. A base is thus added to remove the acid and facilitate the reaction. Unlike in the case of alkylation reaction, the amide formed here does not react further with the organic halide because the amide is nonbasic and a poor nucleophile due to its nitrogen unshared pair of electrons being ..
