Correct Answer: CH2CCI2 and CH2CH2.
Reason:
Structure of compound depends on the hybridization of central atom. In both of the above molecules (i.e. CH2CCL2 and CH2CH2). Central atom i.e. carbon is
sp^2 hybridized. Thus 3 hybridized orbitals of 'C' is involved in sigma bonding. Further, these orbitals are placed spatially at an angle of
. The un-hybridized 2pz orbital of 'C' is involved in pi-bonding. Due to this, both of the above molecules possess a
triangular planner geometry.
Molar mass glucose : <span>180.1559 g/mol
</span>
number of moles:
n = mass solute / molar mass
n = 225 / 180.1559
n = 1.248 moles
therefore:
Molarity = moles solute / volume
Molarity = 1.248 / 0.825 => <span>1.513 M</span>
As the blades rotate, they experience frictional forces as they `rub' against the air; this knocks electrons around, causing the blades to build up a net charge. The charged dust particles then stick to the charged areas of the blades. "The leading edge of the blades usually develops the thickest layer of dust.
