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
The spectrum of He is expected to be similar to: (1) H (2) Li + (3) Na (4) He + Ans: Li +
Chemical Properties of Ethers Ethers are fairly stable compounds. These are not simply reacted along with alkalies, dilute mineral acids, active metals, oxidising agents within
The minimum amount of energy needed for the reaction to takes place is known as threshold energy.
Q. Explain about Neutral and Amphoteric oxides? Neutral oxides have neither acidic nor basic properties and when dissolved in water, they give neutral solutions, e.g., CO, N
