Question

Match the column :
`{:("Column I","Column II"),((A)"Cubic",(p)"Have 2-fold axis of symmetry"),((B)"Orthorhombic",(q)"Have all axial angles identical "),(( C)"Tetragonal",(r)"Have all edge lengths identical"),((D)"Rhombohedral",(s)"More than one types of Bravias lattices are found"),(,(t)"Found in "CaCO_3):}`

Answer 1

Correct Answer - A-p,q,r,s ; B-p,q,s,t ; C-p,q,s ; D-p,q,r,t
`{:("Crystal System","Edge lengths","Axial angles","Type of cell units"),("Cubic",a=b=c,alpha=beta=gamma=90^@,"SC,BC,FC"),("Orthorhombic",anebnec,alpha=beta=gamma=90^@,"SC,BC,FC,EC"),("Tetragonal",a=bnec,alpha=beta=gamma=90^@,"SC,BC"),("Rhomobohedral",anebnec,alpha=beta=gammane90^@,"SC"):}`
