Explain the factor on the basis of which tin dichloride and lead dichlorides are more easily
formed as compared to tin tetrachloride and lead tetrachloride.
Answers
Answer:
Tin(IV) chloride, also known as tin tetrachloride or stannic chloride, is an inorganic compound with the formula SnCl4. It is a colorless hygroscopic liquid, which fumes on contact with air. It is used as a precursor to other tin compounds.[1] It was first discovered by Andreas Libavius (1550–1616) and was known as spiritus fumans libavii.
