Lumpy.
Once you get beyond a single central atom, in general there isn't a simple way of describing the shape. The methyl group will be essentially tetrahedral and the carbonyl carbon will be flat (trigonal planar), but the overall molecule doesn't have a simple shape.
The molecular shape name for C3H8 is a tetrahedron.
Parent Shape: Trigonal bipyrimidal Actual shape: Trigonal Planar
The molecular shape of a magnesium hydride molecule is linear. Magnesium has a +2 charge, while hydride has a -1 charge, resulting in a linear molecular shape.
Trigonal pyramidal
The bond angle in silicon disulfide (SiS2) is approximately 105 degrees, and the molecular shape is bent/angular.
The molecular shape of SCl6 is octahedral.
The molecular shape name for C3H8 is a tetrahedron.
Parent Shape: Trigonal bipyrimidal Actual shape: Trigonal Planar
V-shape
A compound that does not have a bent molecular shape is carbon dioxide (CO2). It has a linear molecular shape due to the arrangement of the three atoms in a straight line.
AlCl3 will take Cl out from CH3COCl which becomes CH3CO+. CH3CO+ is an electrophillic thus attracting to the negative ring of benzene. To form a ketone-Phenylethanone. CH3COCl + AlCl3 = CH3CO+ and AlCl4- . C6H6 + CH3CO+ = C6H5COCH3 + HCL.
The molecular shape of CIF2 is linear. This is because there are only two atoms bonded with the central atom, which results in a linear molecular geometry.
The molecular shape of a magnesium hydride molecule is linear. Magnesium has a +2 charge, while hydride has a -1 charge, resulting in a linear molecular shape.
