Fledespar - KAlSi 3 O 8- NaAlSi 3 O 8- CaAl 2 Si 2 O 8 Zeolites - NaAlSi 2 O 6 ⋅ H 2 O mica - KAl 3 Si 3 O 10( OH )2 asbestos - Mg 3 Si 2 O 5( OH )4 These all are silicates having basic unit ( SiO 4)4-

Q. The basic structural unit of feldspar, zeolites, mica, and asbestos is :

$(S i O_{3})^{2 -}$

$S i O_{2}$

$(S i O_{4})^{4 -}$

Fledespar - $K A lS i_{3} O_{8} - N a A lS i_{3} O_{8} - C a A l_{2} S i_{2} O_{8}$
Zeolites - $N a A lS i_{2} O_{6} \cdot H_{2} O$
mica $- K A l_{3} S i_{3} O_{10} (O H)_{2}$
asbestos $- M g_{3} S i_{2} O_{5} (O H)_{4}$
These all are silicates having basic unit $(S i O_{4})^{4 -}$

Q. The basic structural unit of feldspar, zeolites, mica, and asbestos is :

(SiO3​)2−

SiO2​

(SiO4​)4−

Fledespar - KAlSi3​O8​−NaAlSi3​O8​−CaAl2​Si2​O8​ Zeolites - NaAlSi2​O6​⋅H2​O mica −KAl3​Si3​O10​(OH)2​ asbestos −Mg3​Si2​O5​(OH)4​ These all are silicates having basic unit (SiO4​)4−

$(S i O_{3})^{2 -}$

$S i O_{2}$

$(S i O_{4})^{4 -}$

Fledespar - $K A lS i_{3} O_{8} - N a A lS i_{3} O_{8} - C a A l_{2} S i_{2} O_{8}$
Zeolites - $N a A lS i_{2} O_{6} \cdot H_{2} O$
mica $- K A l_{3} S i_{3} O_{10} (O H)_{2}$
asbestos $- M g_{3} S i_{2} O_{5} (O H)_{4}$
These all are silicates having basic unit $(S i O_{4})^{4 -}$
