1.Temperature :- With increase in temperature the rate of vaporization also increase thus it creates more pressure. Moreover with increase in temperature the kinetic energy of the vapours also increase. 2. Nature of liquid:- The liquids with lower inter-particulate attractions have high vapour pressure as the formation of vapours is easy . Like acetone is easily vaporized as compared to […]
Why is breaking of C-H bond given more preference over C-C bond though the bond energy of the latter is less than the first one?
In case of hydrocarbons , the c-c bond is normally safe due to following two reasons :- Difference between the electronegativity of Carbon and Hydrogen. Due to this reason the electrons of the shared pair stays closer to the C-atom which makes it easy to break the C-H bond and release hydrogen as hydronium ion H+ . 2. The carbon […]
There is a trick in learning this reaction I will make it very easy for you to learn and rewrite. Firstly see the reaction:- Na2CO3 + 2HCl → 2NaCl + CO2 + H2O Tricks to learn:– Firstly see the formula of carbonate its CO3 , this will be converted into CO2 , One oxygen of CO3 will attach to two […]
Valency :- “It is the combining capacity of an atom”. it also indicates the number of electrons that can be gained , lost or shared . It decides that how […]
The word mole means pile up . This concept originated from a simple problem that was faced by the scientists to calculate the reactions. they needed a concept that could […]
