For the energy levels in an atom, which one of the following statements is correct?
The second principal energy level means n=2 .So second orbit can have s orbitaland p orbital ,so s orbital have 1 sub level and p can have sub levels totally second orbit has 4 sub energy levels and contain a max of 8 electrons (4x2=8).
BCl3 is a planar molecule because in this molecule boron is
BCl3 - Boron Trichloride:
BCl3 is electron deficient molecules having six electrons in the valence shell of their respective central atoms
To complete their octets, the central atom in each case can accept a pair of electrons from the chlorine atom of another molecule froming dimeric structures.
However, because of small size of B, it cannot accommodate four big sized Cl atoms around it.
Therefore, BCl3 prefers to exist as monomeric planar molecule in which B atom is sp2 hybridized
The enthalpy of combustion of C(graphite ) and C (diamond) are -393.5 and -395.4 KJ mol⁻1 respectively .The enthalpy of conversion of C(graphite) to C (diamond) in KJ mol⁻1 is
If one mole of an ideal gas at 27oC temperature is compressed reversibly from 20 litres to 10 litres, then work done during the process is (R=8.314J-K⁻1-mol⁻1)
IUPAC name of Na₃[Co(NO₂)₆] is
Hence D is correct.
The equilibrium in the reaction Cr₂O₇2⁻ → 2CrO₄2⁻ is shifted to right in
