1.	Which of the following is true regarding the thermal stability of halides of Carbon family?(a) CX4 > Si X4 > Ge X4 < Sn X4 > Pb X4(b) CX4 > Si X4 > Ge X4 > Sn X4 > Pb X4(c) CX4 > Si X4 > Ge X4 > Sn X4 < Pb X4(d) CX4 < Si X4 > Ge X4 > Sn X4 > Pb X4I had been asked this question in unit test.The doubt is from p-Block Elements in portion p-Block Elements of Chemistry – Class 11
Answer» Right CHOICE is (b) CX4 > Si X4 > GE X4 > SN X4 > Pb X4 The explanation: All the elements of Carbon family give tetrahedral and covalent halides of the type MX4. The THERMAL stability follows in the decreasing order of CX4 > Si X4 > Ge X4 > Sn X4 > Pb X4 for the elements of group 14.
