Diborane

Diborane Structure

Preparation: 4BH3 + 3LiALH4 → 2B2H6 + 3LiF + 3AlF3 2NaBH4 +I2 → B2H6 + 2NaI + H2 2BF3 + 6NaH → B2H6 + 6NaF Structure: Diborane contains four terminal and two bridging hydrogen atoms The terminal H atoms and B atoms lie in one plane. The bridging H atoms lie above and below the plane Properties: Colourless highly toxic gas B.P : 180 K Catches Read more about Diborane Structure[…]

Isobaric process

Application of First Law of Thermodynamics on Different Process – II

Isothermal process:- The process in which temperature remains constant is called isothermal process. But practically isothermal process is impossible, because for a isothermal process to occur there should be infinite conductive material, which is not possible. For this purpose only we perform a work slowly so thatExternal work done by an ideal gas in isothermal Read more about Application of First Law of Thermodynamics on Different Process – II[…]

Cyclic Process

Application of First Law of Thermodynamics on Different Process – I

Application of first law of Thermodynamics on different process we have the different process like.  Cyclic process  Isolated process  Isothermal process  Isobaric process  Isochoric process  Adiabatic process Cyclic process:- When a system is taken form an initial state to other state and finally brought back to the initial state, then it is called “Cyclic Process”.

Quadrant

Cartesian co – ordinate system in plane – I

RECTANGULAR CO-ORDINATE AXES: Let X’OX and Y’OY be two mutually perpendicular lines through any point O in the plane of the paper. We call the point O, the origin. Now choose a convenient unit of length and starting from the origin as zero, mark off a number scale on the horizontal line X’OX, positive to Read more about Cartesian co – ordinate system in plane – I[…]
