Properties of Styrene Styrene is a colourless liquid, boiling point 145°C. On keeping, it slowly changes into a solid polymer known as meta styrene. The polymerisation is fast
why exception is seen in lanthanoids
Explain terminal carbons and central carbons The terminal carbons are bound to three groups, and are thus trigonal planar. The central carbon is bound to two groups, and is
