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.

Hello all,  today I explained the satellites. study carefully. satellite is nothing but an object that revolves around the planet in a curved path. satellites are two types: natural satellites(the moon is a satellite because which revolves around the earth) artificial satellites(human-made) coming to the topic of artificial satellites; artificial satellites are made by the human and launched by the human through the rockets into the orbit of the planet. the satellite launching involves two steps: the satellite has to be taken into the desired altitude. pushed out from the spacecraft at the right velocity to begin and maintain it's orbit. the satellite launch vehicle moves straight only for a few seconds. A satellite launch vehicle is a multistage rocket, consists of a smaller booster rocket for boosting. boosters give the rocket initial thrust during the launch and carry the vehicle rarely part of the flight. when the fuel completed in the boosters they fall away from the rocket ot...
