Define reactivity
The tendency of an element to attain a completely filled outer shell or a noble gas electronic configuration
Covalent bonds are strong ___________ but have _____ inter molecular forces
1, Strong 2.weak
Organic compounds `
carbon compounds usually containing hydrogen and one or more other elements such as oxygen sulphur nitrogen chlorine etc
Hydrocarbons
Organic compounds of carbon and hydrogen
Covalent bonds
A chemical bond formed between 2 atoms by mutual sharing of electrons to acquire the electronic configuration of the nearest noble gas element
Covalent compounds
Compounds formed by sharing of electrons
Covalency
The no of electrons that an atom of an element shares with other atoms of the same or different element to gain inert noble gas electronic configuration/ forming a covalent molecule
Covalent compunds are _________ in naturw
tetravalent
Physical state
Single-molecule most of the time in gaseous state
Ex-Cl2 H2 CH4 NH3 So2
Also liquid Br2
Some solid I2 P4 S8
Melting and boliong oint
Less as ions are not present and attractive frces are weak In homo series it increases with increase in molecular mass
Electrical conductivity
Poor ex HCL when dissolved in water
Nature
Molecular form hehe
Solubility
Not soluble in water but covalent or organic solvents tetrachloride- CCl4 Benzene acetone
