What is the appearance of sulfur dioxide?
Sulfur dioxide appears as a colorless gas with a choking or suffocating odor. Boiling point -10°C. Heavier than air. Very toxic by inhalation and may irritate the eyes and mucous membranes.
What is the structure of sulfur dioxide?
SO2 molecule has a bent structure with an O–S–O bond angle of 119°. Sulphur is sp2 hybridised and the lone pair of electrons of sulphur reduces the bond angle from 120° to 119°. In the structure, each oxygen atom is attached to sulphur by an σ and a π bond.
What is the shape of Sulphur dioxide molecule?
One sigma and one pi bond are formed for the bonding between the sulphur and two oxygen atoms. The atom will also accommodate one lone pair….What is SO2 Hybridisation?

What is the Colour of Sulphur trioxide?
colorless
Sulfur trioxide, is a colorless to white crystalline solid which will fume in air.
What is the Colour of sulphur trioxide?
Is sulfur dioxide bent or linear?
Carbon dioxide is linear, while sulphur dioxide is bent (V-shaped). In the carbon dioxide, the two double bonds try to get as far apart as possible, and so the molecule is linear.
Why is SO2 trigonal planar?
For example, sulfur dioxide, SO2, electron-domain geometry is trigonal planar. This is because it has 3 electron domains – the 6 valence electrons for sulfur form 2 single bonds with 2 oxygen atoms and sulfur has one non-bonding lone pair. The polarity influences the bond angle for the bent geometry.
Is SO2 bent or linear?
1. Carbon dioxide is linear, while sulphur dioxide is bent (V-shaped). In the carbon dioxide, the two double bonds try to get as far apart as possible, and so the molecule is linear.
What is the electron geometry for the sulfur in sulfur dioxide?
The 4 electron pairs are at the corners of a tetrahedron. The electron pair geometry is TETRAHEDRAL.
How do you identify Sulphur dioxide gas?
Sulphur dioxide is a dense colourless gas, which is soluble in water, and has a suffocating and unpleasant smell of burnt matches. It has a melting point of -72.7°C, and a boiling point of -10°C. Sulphur dioxide gas can be made directly by heating its constituent elements.
