ALKANES AND ALKENES,ALKYNES

ALKANES: these are also called paraffin. alkanes are saturated hydrocarbons. the formula of alkanes (CnH2n+2). when the H atom is removed from the alkane then it is replaced by the name of alkyl. the formula for alkyl is (Cn H2n+1). the carbon atom in it shows the sp3 hybridization. the bond length is equal to 1.54°A. ALKENES: these are also called as olefins means form oil products. it possess a double bond between them. the formula is (CnH2n). the carbon atom in it shows the sp2 hybridization. the bond length is equal to 1.34°A. ALKYNES: these are also called as acetylenes. the formula for this is (Cn H2n-2). the carbon atom in it possesses a triple bond and also shows the linear shape means it is in an sp hybridization. the bond length is equal to 1.20°A.

THERMODYNAMIC LAWS

 HELLO ALL, TODAY I WANT TO EXPLAIN ABOUT THE THERMODYNAMIC LAWS thermodynamic laws are : 1. first law: it states that energy neither be created nor be destroyed, it always changes one form to another form. 2. second law: it states that energy can change the position of any object but the state of energy is potentially reduced comparing to the initial state. 3. third law: it states that the thermal energy per unit temperature of a system approaches a constant value as the temperature absolute zero. zeroth law: if two systems are in thermal equilibrium with the third system then these three are also in thermal equilibrium.
