Designing a Synthesis

Organic synthesis is a branch of chemical synthesis that involves the planned construction of organic compounds/molecules from smaller units that possess functional groups. Friedrich Wöhler was the first scientist who designed the synthesis of an organic compound, urea from inorganic starting materials silver cyanate with ammonium chloride via a simple, one-step synthesis.

Like alcohols, ethers undergo a cleavage by breaking a carbon–carbon bond between an alkyl group and the carbon bonded to the ether oxygen atom; that is, the red C–C bond in R–CH2OR' is broken.

2. What is the effect of a tert-butyl group when placed in a 6 membered ring? I've been told it "locks" the conformation but I don't understand what that means exactly. Does it have an effect on reactivity? Does it just mean the ring cannot undergo a ring flip? For example, in the reaction below would the ketone reduce to an alcohol as normal, as though the tBu group LIAIH4 *tBu wasn't there?
