What is regiochemistry of saytzeff elimination

Answer»

e BOND is formed due to loss of water molecule. It is an eliminationreaction. According to Saytzeff's RULE(also Zaitsev's rule), during dehydration, more substituted alkene (olefin) is formed as a MAJOR product, since greater the substitution of double bond greater is the STABILITY of alkene.

Why is acetic acid is called glacial acetic acid

Answer»

e here is your answer.Acetic acid that contains a very low AMOUNT of WATER (LESS than 1%) is called anhydrous (water-free) acetic acid orglacial acetic acid. The reason it's called glacial is because it solidifies into solidacetic acid crystals just COOLER than room temperature at 16.7 °C, which ice.thank you.plzzzzzzzzzzzzzzzzzzzzzzzzz mark my answer as brainliest.plzzzzzzzzzzzzzzzzzzzzzzzzz follow me.

In B2H6 there are BHB bonds which are 3 centered 2 electron bond .what is meant by this

Answer»

e here is your answer.Three-center two-electron bonds are seen in many boron compounds, such asdiborane (B2H6). The monomer BH3 is unstable SINCE the boron ATOM is only surrounded by six valence electrons. ... The two electrons (corresponding to onebond) in a B−H−B BONDING molecular orbital are spread out across three INTERNUCLEAR spaces.thank you.plzzzzzzzzzzzzzzzzzzzzzzzzz mark my answer as brainliest.plzzzzzzzzzzzzzzzzzzzzzzzzz follow me.

Hey friends tell me about Principle quantum number which are in class 11 from chemistry

Answer»

ncipal quantum number is the quantum number denoted by n and which indirectly describes the size of the electron orbital. It is always ASSIGNED an integer value (i.e., n = 1,2,3,...), but its value MAY never be 0. An orbital for which n = 2 is larger, for EXAMPLE, than an orbital for which n = 1. Energy must be absorbed in order for an electron to be excited from an orbital near the nucleus (n = 1) to get to an orbital further from the nucleus (n = 2).The principal quantum number is cited first in the set of four quantum numbers associated with an electron. The principal quantum number has the greatest effect on the energy of the electron. It was first DESIGNED to distinguish between DIFFERENT energy levels in the Bohr model of the atom but remains applicable to the modern atomic orbital theory.
