Explanation:
Elements bond to each other by either (loosing / gaining) or sharing electrons with each other .
When bond is formed by loosing or gaining electron between metals and nonmetals then that type of bond is called ionic bond or electrovalent bond. Examples :-Nacl, Kcl etc..
When bond is formed between two elements that are non metals and bond form in between is due to sharing of electrons equally is called covalent bond.ex- Ccl4 , Sicl4 etc.
When bond formed between elements are shared unequally between atoms of elements then it is called co-ordinate bond. Ex:- No2, HCl etc..
Some people think about Metallic bond it's pretty simple actually it takes between same metal lattice. Definition is as follows
A metallic bonding is defined as where electrons freely move around a metal lattice (the metal atoms close united) to form a bond between the entire metallic element.ex:-Na, Mg and all other S , d and f block elements .
Last but not the least , Take case of hydrogen bonding it takes Place between H and electronegative elements like ( o , F , Cl , N ) etc examples are Hf , HCl , h2O etc.
Hope you have got the idea.
Answer:
the significant of carbon.A compound found mainly in living things is known as an organic compound make up the cells and other structures of organism and carry out life processes.Carbon is the main element in organic compound,so carbon is essential to life on earth
Answer:
See explanation and Image attached
Explanation:
The preparation of triphenylmethanol occurs as shown in the image attached to this answer.
The first step is the nucleophillic reaction of the phenyl magnesium bromide with the carbonyl group.
Reaction of the second molecule of phenyl magnesium bromide with the product yields triphenyl methoxide ion. Reaction with acid yields the triphenylmethanol product which is extracted into the organic phase.
The triphenylmethanol product can be purified by recrystallization.
