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.

THE STARSHIP(SPACE-X) JOURNEY OF EARTH TO MARS

space x is a private company. The founder of this company is Elon Musk. What is the Starship program? The specific Starship gets to Mars and back to the earth. the starship is a spacecraft.  Space x's grandest upcoming rocket was once known as the interplanetary transport system. the big Falcon rocket  but most recently it has settled on the name Starship. space x founder Elon Musk has announced a complex and ambitious plan to put crewed starships on Mars in the coming decades.  The plan involves several flights and re flights of both Starship vehicles and the super-heavy boosters. Ultimately the goal of Elon Musk is to have a system through which hundreds of people at a time can travel to Mars.  Whether to colonize or just to visit, at a relatively low cost. if the system of Elon Musk proposes really does run at optimal speed, like a well-oiled train line, interplanetary travel May become something we begin to see a lot more of an important part of the space fairing...
